ABSTRACT
Introduction: The Czech Republic (CR) is a country with the high mortality due to COVID-19 from a global perspective. Despite its robustness, the health care system was overloaded several times. Aim(s): We want to find out which factors were associated with the risk of severe covid (SC, ie ICU stay or death) in the population of the CR. Method(s): The whole population analysis was based on data (related to all-cause mortality, hospitalization/intensive care, comorbidity burden-CCI, age/gender) collected by the Institute of Health Information and Statistics of the CR via the National Health Information System. Multivariate logistic regression was used to evaluate the influence of interest parameters. Result(s): We analysed data of 153.783 patients (pts) aged 40+ hospitalized due to primoinfection and had valid data (average 71yrs;52 % males). 30.502 (19.8 %) pts stayed at ICU. Every fourth (35.746;23.2 %) hospitalized patient died. Females (OR 0.66), and >80yrs (OR 0.56) had lower probability to be hospitalized in the ICU than males and pts 40-49 yrs. Comorbid burden (CCI 1;2;3-4;5 and more) was associated with a slight increase (OR 1.10;1.18;1.23;1.14) in the likelihood of being hospitalized in the ICU. Females (OR 0.63) had lower probability to SC. Contrary increased age (50-59;60-69;70-79;>80), respectively higher CCI (1;2;3-4;5 and more) were associated with strong rise (OR 1.29;1.67;1.93;2.48) resp. (OR 1.14;1.30;1.50;1.90) of SC risk. Conclusion(s): Older age, multimorbidities are associated with a strong probability of SC, however, the level of care at the ICU does not fully correspond to this.
